Hi Dear, Welcome to HCM. The symptoms you mention in query are clearly showing that there is a formation of dental abscess or endodontic abscess . An abscess is an area of pus that forms as part of the body s effort to fight a bacterial infection. The bacteria can enter the tooth from upper surface in the form of caries and form abscess at root tip . Sometimes bacteria can enter through gums and cause infection . There can be many treatment options for dental abscess like root canal treatment , drainage of abscess or antibiotics course (amoxicillin) for 7-10 days . As you already book appointment with dentist , but its too late try to consult another dentist fr earily appointment . you should take care of certain things till then . Avoid brushing at that particular site , wash that site with warm water , do warm saline rinses several times a day , maintain proper oral hygiene and do betadine rinses twice a day to prevent infection from spreading . Take ibuprofen or acetaminophen for pain and swelling . Hope your concern has been resolved. Get Well Soon. Dr. Harry
